COMBINATION ENVELOPE Fila Oct. 6, 192a Patented Aug. 5, 1930 UNITEDSTATES PATENT OFFICE CHARLES W. FRASER, or TORONTO, ONTARIO, CANADA,ASSIGNOR' TOTHE GEORGE EVERALL COMPANY, LIMITED; or TORONTO, OANAD VCOMBINATION ENVELOPE Application filed October 6, 1928. Serial No.310,763.

This invention relates to double purpose envelopes and has for itsobject the construction of an envelope of the type described which maybe cheaply and easily made and 5 which is convenient and simple for use,which maybe made from a minimum amount of material, and in whichthe-insertion of the contents and closing the envelope is facilitated.

I attain my object by constructing an envelope of comparatively largesize for pamphlets catalogues or other second class mail, which envelopeis left open at two adjacent sides, each of the open sides beingprovided with a flap, one of which is gummed for sealing purposes.

To the inside of the envelope a sheet of paper is secured to form acompartment for letters or other first class mail. The open side of thiscompartment is arranged sufficiently close to the open side of theenvelope having the gummed flap, so that when the flap for that side ofthe envelope is sealed down, the open side of the compartment 1S'1I1-accessible. The other flap of the envelope is simply slipped within theenvelope to prevent accidental slipping out of the pamphlet, catalogue,or'other second class mail.

With this construction both classes of mail may be insert-ed from oneside ofthe envelope, thus avoiding the necessity of turning theenvelope, while at the same time a very large opening extending over twosides of the envelope is provided. This not only greatly facilitates theinsertion of the second class mail but makes the opening of the firstclass mail compartment more easily got at.

The invention is hereinafter more fully described and isillustrated inthe accompany ing drawings in which Fig. 1 is a plan view of theenvelope showing the flaps open; 7

Fig. 2 is a section through the envelope on the line 2-2 in Fig. 1,looking from right to left, showing the envelope in its closed conditionFig. 3 is a plan view of the blank from which the envelope is made;

Fig. l is a longitudinal section partly broken away of an alternativeform of the en velope; and 1 Fig. 5 is an end view of the said modifiedform. v V

In the drawings-like numerals ofreference indicate corresponding partsin the different figures. V

1 represents the front or address side of the envelope and 2 the back ofthe envelope, which is hinged at its lower edge to the frontv of theenvelope. A flap 3 is secured to one. end of the front of the envelopeand sealed over the free edge of the back of the envelope; A flap 4 isprovided at the top edge of the back of the envelope and adhesive matter8 is provided on its free edge wherebyit is adapted to be sealed overthe upper. edge of the front 1 of the envelope.

A fiap 5 is attached tothe frontl of the envelope at the otherendthereof. This flap is adapted to be turned into the opening between thefront and back. or may beiturned over and detachably securedin someknown manner to the back of the envelope.

A partition 6 is glued to the front of the envelope on the insidethereof,preferably adjacent the upper left hand side of the envelope.This partition is secured along three of its edges, but its top is openand adjacent the upper edge of the envelope and is adapt ed tO-be closedand sealed when the flap 4 is turned over and sealed.

The compartment above referred to is adapted to carry a letter or otherfirst class mail. An opening or transparent portion 7 may be formed inthe front 1 of the envelope in such a position as to make a name oraddress written on an inserted letter visible and IOitdilble through thefront 1 from the out sic e.

Suitable directions for theuse of the envelope'may be printed thereonand a space marked for afiixing first class postage for the first classmatter andanother space for postage for the other matter of otherclasses.

- While one specific method of forming the envelope is described, it maybe seen that the construction of the envelope may be varied considerablywithout departing from the gist of my invention, which consists of anenvelope permanently sealed at two adjacent "adjacent sides throughwhich mail matter 2 mans-so sides, and open at the other adjacent sidesfor the insertion of mail matter of different classes, one of the sidesbeing adapted to be I sealed to close permanently the one side of theenvelope and the first class mail compartment, and the other side beingadapted to be closed in such a manner that the second or lower classcontents of the envelope are accessible for inspection by the postalauthoritieS. I

Figs. 4 and 5 show an alternative form of my improved envelope. Inthis'construction the partition 6 is left open adjacent the left handend of the envelope, and" is adapted to be closed by the flap 5, so thatthe letter compartment is accessible as Well as the main interior of theenvelope. Thisconstrnction is useful Where the letter compartment isused to hold circulars etc. hich may be mailed at reduced rates if notsealed.

What I claim is: V

In an envelope, a front and back portion hinged at one side, and havinga flap formed on one portion, adjacent the hinged side, said flapbelng'sealed over the other portion, closing one side, and leaving twoopen may be readily inserted; a flap on one portion' provided withadhesive matter on its free edge whereby it is adapted to be sealed overthe free ed e of the other portion, sealing another side; a partitionsecured along its edges to the inside of one of said portions and havingone free edge near the side of the envelope Which is adapted to besealed by the last mentioned flap, thus forming tWo coterminons openingsadapted to be sealed by the one flap; and afiap on one portion adaptedto close aside of the envelope adjacent the last mentioned side, saidflap being adapted to be releasably held in its side closing position.

Y Signed at Toronto, Canada, this 28th day of August, 1928.

CHARLES FRASER.
